Abstract A B-spline Quasi-interpolation Empirical Mode Decomposition
(BSQI-EMD) method is presented and applied to similarity analysis of
DNA sequences. The B-spline quasi-interpolation is used to
approximate the extrema envelopes during the Intrinsic Mode Function
(IMF) sifting process. The BSQI-EMD method is simple, easy to
implement, and does not require solving any linear system of
equations. Then we implement the classic EMD method and our method
respectively. This work verifies our method's suitability and better
performance for similarity/dissimilarity analysis among the coding
sequences of the first exon of $\beta$-globin gene of ten different
species.
